England's hat-trick hero Stuart Broad said his feat would mean nothing if his side fails to win the second cricket Test here for a 2-0 lead over the India in the four-match series.

"It won't mean anything if we don't win this Test. We need to post a big score. Somebody needs to get a big hundred," said Broad, who took a sensational hat-trick in front of his home crowd, at the post-match press conference on Saturday.

"We need to get 300 and then apply pressure through our seamers. The wicket would have a variable bounce (in the fourth innings)," he said.

Broad, in his sensational spell in the final session, took four wickets from six balls for no run -- including the wickets of Mahendra Singh Dhoni (5), Harbhajan Singh (0) and Praveen Kumar (0) off successive balls.

"We tried to build pressure the whole day. I thought heavy roller (taken by India in the morning), played a huge role. The wicket was quite slow and did not do huge amount of help for us.

"But we wanted to build pressure for here you can have wickets in quick succession. Fortunately, we managed it late in the day. I said yesterday that India had three quarters of the day and it was the same today. Fortunately, we nipped the last session," Broad said.

The tall bowler had words of praise for Rahul Dravid who managed a hundred while opening the innings.

"He played fantastically well. The way he left balls is an example for us. He is hard to bowl, allows the ball to come to him. He had a bit of luck but still it was a fantastic hundred. We were happy to see the back of him.

"It was very pleasing to see him standing at the other end while wickets fell quickly (this end)," said Broad who returned with career-best figures of 6/46.

Broad disclosed that number three batsman Jonathan Trott, who fell over his right shoulder and hurt himself, did not ensure any damage but it is unlikely he would come out to bat till number six.

This is the third hat-trick which Broad has managed during his career although his first since the last one he got at the under-15 level.
